CLOSURE.

Application fled hi a-1924. serm'mi. 723.930.

The present invention provides improved covering; means for closing..receptacles,

jars,-fo1 ,example,such that. they ma be closed'quickly and easily,while desired tight- 6 guess of closure may be effected even though thecovering means be-hurriedly or carelessly applied. 1

y he nature of the invention will be readily understood by reference toone practical eml -bodiment of the invention, which is shown,

for illustration, in the accompanying drawin s in which:

ig. 1 is a sectional elevation of the open end of a jar and its closure,the latter being shown in the position occupied when fully seated overthe mouth of the jar;

Fig. 9;, a view similar to Fig. 1, shows the closure applied to a jar,but only partially seated over the mouth thereof;

Fi 3 is another sectional elevation, showing t e closure applied to thejar in a tilted position, and only partially seated, to illustrate theefl'ect of careless application of the closure.

Jar covers and the like heretofore have been open to certain objections,that apply with particular force to counter displayand dispensing jarsor other receptacles, which.-

are intended to be kept tightly-closed, but

so which sales people are required to open and close frequently inmaking retail sales. With reference to these objections, it' may hesaid. that covers which have been capable ofmak ing adequately tightclosures when carefully applied, have involved somewhatcompli catedprocedure in applyino them. Screw topsfall in this category. l f wellfittedand thoroughly screwed down, they will form satisfactorily tightclosures. But the aver-' 0 age sales person, in the haste ofretailtrade, is likely not to seat the top fully, to leave it onlyresting upon the jar mouth or partially screwed down so thattightclosure is lacking. Furthermore, those covers which 46 are easily andquickly applied and removed (e. g., without being screwed on or oil) donot close the jars adequately ii carelessly applied The presentinvention aims to avoid these 5o objections, in a cover which may beeasily applied and removed.

- Referring to the accompanying drawings,

the illustrative'embodiment of the invention includes a cover i appliedto the mouth ms of a jar or the like.

and held against ionv Disregarding for the present the particum ARIDOR'company, or

lar fprm and material of the cover and of the ar mouth, the directcooperation. bei tween the two is characterized by a resilient wall 6on'one of the parts, arranged to form a. tight closure with the otherpart.

As shown, the resilient wall 6, carried by the top 4, is in the form ofadepending annular flange having a convert or torus-like inner surfaced,The leastYdiameter of the annular convex inner surface of the wall 6, e.g'., between the points a,, and h, Fig. 2, is slightly'less than theoutside diameter of the jar mouth with which the resilient wall isintended to be engaged. With this arrangemerit, if the cover 4: ispressed down upon the jar mouth, the resilient wall will he compressedin cross section and will be made to grip the outer suriace oi the jarmouth.

From the points a and l), the convex surface 7 recedes to provide anenlarged circular opening at the lower extremity of the wall to receivethe jar mouth when the top is initially applied; and also an enlargedannular space to receive the jar mouth when w the top is fully seatedover the mouth of the jar.

The mater al oiiwh ch the wall is formed may be of such cons stency asto retain its normal sha "e. and atthe ,sarne,v time possesssuiiicie'nt" pliability to be readily compressed,

sons to adaptitselif to the form off-the jar mouth at whatever angle thecover may he,

placed thereon.

lnthe specificemhodiment shown, the re silient wall 5 comprises a gasketof rubber or the like which maybe positioned within a dependingwallportion oi the cover i,

a tudinal displacement with reference thereto or,"

. 9 adja cent its upper or inner e and v y a narrow inwardly extendingannular flange ill formed on the lower or outer edge of the wallportion. 8.

The wall 6 may he provided on its outer, surface with a relativelyloroad annular groove 11, thereby, producing a wall of cone; cavo-convexcross-sectional form which, in, addition to being compressible as above.mentioned, is capable also oi? heing distorted laterally when placedover the jar mouth.

It will be observed-that when thegasket is placed within the cover l, asshown, the, concave surface of the annular groove l1- on the outersuriaceoiE-the wall 6 will form an annular hollow chamber between thewall and the inner surface of the wall portion 8 of the cover to providesuflicient space for the maximum distortion or bulgin of the wall 6 ofthe gasket when the cover 1s placed upon the jar.

If desired, the wall 6 may be provided with an additional jar engagingsurface in the form of a laterally and inwardly extending annular-flange12, preferably at its upper or inner edge and adjacent the shoulder 9 ofthe cover 4.

It will be observed that when the cover and gasket in the formillustrated in the drawings, are positioned on the jar in proper ali enttherewith, as shown in Fig. 1, and in y seated over the mouth of thejar, there will be two separate areas of contact established between thegasket and the open end of the jar, i. e. where the wall 6 engages theouter annular surface of the jar mouth 5, and where the edge of the jarmouth engages the flange 12. The annular wall 6 of the gasket, by reasonof its resiliency grips the outer annular surface of the jar mouth and,in addition to establishing a tight connection between the cover andjar, assists in preventing the accidental displacement of the cover. 1

To further assist in reventing the accidental displacement of the coverand to provide a more efiicient connection between the cover and jar,the neck portion of the latter may be provided with a narrow annularflange or flattened bead 13, andwhen the cover and gasket are placedover the mouth of the jar, the gasket, by reason of its pliability andresiliency, will be compressed or bulged outwardly as above described,and when the cover is pressed home will resume a position in back of thebead (see Fig. 1) thereby assisting, in a measure, the frictionalcontact between the gasket and jar in resisting removal of the cover,and providing additional surface for the contact of the gasket toprevent the admission of air. This also assists in holdin down the coverwith a tight connection tween the flange 12 and mouth of the jar.

The H 12 in addition to providing a seat for the outer edge of the jarmouth,

tends to stiffen the inner edge of the wall 6 and prevent any possiblecollapsing, or withdrawal of the gasket from the cover when the latteris removed from the jar.

It will be observed that no matter how the closure is placed on the jar(see Figs. 2 and 3), a substantially air-tight connection is establ shedbetween the jar and closure; the pressure incidental to the mere.placing of t e closure on the jar being suflicient to to distort orcompress the wall 6 of the gasket to provide contact throughout theperiphery of the jar mouth.

In the use of the present invention, no

appreciable amount of time or care is required in placing the closure onthe ]ar to insure a proper connection therebetween, for even though theclosure be carelessly applied the jar immediately is made substantiallyair-tight. This is highly important and most desirable when jars or thelike equipped with such closures are used as dispensing receptacles instores, candy shops and Obviously the present invention is not.

limited to the particular embodiment thereof herein shown and described.
